VALVE.

Application filed March 29, 1926. Serial No. 98,257.

By way of explanation, it may be stated that a person rarely puts the plug in a publie washbowl, permits water to collect in the bowl, and Washes his hands in the water thus collected. Rather, the custom is to wash the hands in running water, the result being that the hands have to be shifted from hot water to cold water, with uncomfortable consequences. The foregoing being true, this invention aims to provide a novel means whereby a iniXture ofcold and hot water may be permitted to flow from the spigot tor a period of time which may be determined.

It within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings Figure 1 shows in elevation, a device constructed in accordancewith the invention and mounted on a washbowl; Figure 2 is a section of the valve mechanism; Figure 3 is a section on the line of Figure 2; Figure 4 is a section showing a modification; Figure 5 is a section showing another modification; Figure 6 is asectionon the line (S-(i oi Figure 5; Figure 7 is a sectional view disclosing the timing valve; Figure 8 is a section showing another modification; Figure 9 a perspective view of thestrueture disclosed in Figure 8; Figure 10 is a perspective view showing another modification.

Referring to Figures 1, 2 and 3, the numeral 1 marks a washbowl. The wa-shbowl 1 has a drain 2. The back of the Washbowl is marked by the numeral 3. i

In carrying out the invention, there is pro- The casing 4is closed at its upper end by a removable'plug 5. The casing 4 has a lower partition 6. The partition 6 terms a lower chamber 7 in the casing 4. The casing 4 has an intermediate parti tion 8. The intermediate partition 8 forms an intermediate chamber 9 between the partition 8 and the lower partition 6. The lowcr partition 6 carries an upstanding tubular seat 10. The seat 10 communicates at its lower end with the chamber 7. The partiion 8 carries an upstanding tubular seat 11. An upper chamber 12 exists in the casing 4 about the tubular seat 11. A cold. water inlet pipe 14. is joined to the casing 4. The cold water inlet pipe 14 communicates with the chamber 12. There is a valve 15 in the cold water pipe 14. The valve 15 is under the control of an operator, to regulate the amount of Water that passes through the pipe 14. A hot water pipe-16 is connected to the casing 4. The hot water pipe 16 communicates with the chamber 9. There is a valve 17 in the hot water inlet pipe 16. The valve 17 is under the control oi an operator. It regulates the amount of hot water that passes through the pipe 16. By a proper manipulation of the valves 15 and 17,with respect to each other, the temperature of the mixture othot and cold water may be regulated.

"i sliding valve 18 is mounted for reciprocation in the casing 4. When the valve 18 is in its lowermost position, as shown in Figure 2, it closes the seat 10, the chamber 9, and the chamber 12. A by-pass 19 connects the cold water inlet pipe 14 with the casing 4 at a point above the valve 18. There is a seat 20 in the by-pass 19. The seat 20 cooperates with a timing valve of any desired kind. It preferred, the valve 21 may be used, the same being carried by a screw 22 threaded into a plug 23 mounted in the by-pass.

A pipe 24 communicates at its lower end with the chamber 7. The pipe teri'ninates' in a tta'ncet 25 discharging into the bowl 1. A pipe 26 conmiunicates with one side of the; casing 4, at a point above the valve 18. A pipe-27 is branched off from the pipe 24. The pipes 26 and 27 are joined at their upper ends by a valve casing 28. The'pipes 26 and 27 may be alluded to as a U-shaped or loop-shaped pipe in which a valve casing (28) is interposed. The valve casing 28 has a transverse partition 29. The partition 29 is located between the upper ends of the pipes'26 and 27 It has an opening 30. The opening 30 is adapted to be closed by a valve 31. The valve 31 is mounted on a stem 32. The stem 32 slidesin a gland 34 carried by the casing 28. The compression spring 33 surrounds a portion of the stem ltll) 32. One end of the spring 33 abuts against the gland 3st. The other end of the spring 33 abuts against the valve 31. The function of the spring 33 is to maintain the valve 31 seated on the partition 29, to close the opening 30. The stem 32 is accessible through the back 3 of the washbowl 1.

in practical operation, the operator unseats the valve 31 by pulling outwardly on the stem 32 and holding it for a moment. -When the stem 32 is released, the spring 33 closes the valve 31 on the opening 230 in the partition 29. l t hile the valve 31 is opened, pressure in the casing 4;, above the valve 18 is released. The valve 18 moves upwardly, because there is a full head of water beneath it, derived from the pipes i l and 16. W hen the valve 18 moves upwardly, the water in the casing a, above the valve 18, flows through tie pipe 2 ii to the casing 28, through the opening 30, out by way of the pipe 27, into the pig e 2%, and away b? means of the faucet 'Vhen the valve it; moves upwardly, cold ater lows from the pipe i i, and hot water flows itron'i the pipe 16, the hot and cold wate" mingling in the casing- 4, below the valve 18, the mixture oi. water passing downwardly through the seat 10, into the chamber 7, and through the pipe to the spigot a mixture or hot and cold water thus bring delivered to the ope ator by a simple in vement which consists in pulline' valve stem 32 outwardl As hereo 1. l J 1, l. inbelore po nted out, the pro iiorti n ilO-L water and ctld water n y be changed by shifting one or both ot i e valves and and these valves, furthermore, govern the amount of water that is supplied. The length of time that the water is to flow, is regulated by the position of the adjustable valve 21 with respect to the seat 20. The water liows from the pipe lilthrough the by-pass 15) into the casing el, about the valve 18, and the valve thus is caused to seat, after an interval, the length of which. is regulated by the position of the valve 21.

Referring to Figure there is shown a casing The upper en-c of the casing is stopped by a closure plug 36. 'lhe casing 35 has a lower partiti n 37. There is a lower chamber 38 in the casing 35, below the parifon 37. The casing has an intermediate partition There is an intcrmediate chamber 40 between the partitions and 3'5. There is an upper chamber all above the intermediate partition 39. The lower partition 37 carries an upstanding tubular "t extended through the cl'ians .18 intermediate partition 39 has un u istanding tubular seat 43 disposed about the seat 452 and extended upwardly through the. chamber 4-1.

Cold water fie vs from the pipe 4H; into the chamber 41, and thenc 1 into the casin 3 below the valve 418, which has been elr 'atedi Hot water flows from the pipe 46 into the chamber 38, andthroug'h the seat 42, i the asinp; 35, below the valve 4:8, which has been elevated. Hot and cold water become mixed and 'llOW downwardly into the chamber 40, the mixture leaving by way of the pipe 54 and passing; to the point of use. l l hen the pressure builds up in the casing 35, above the valve l8, the valve t8 closes to the position shown in Figure 1, and cuts off the sup ply of hot and cold water. The pressure builds up in the casing 35, above the valve 48, through the by-pass49, under the govern ance of the valve 51, it being possible to adjust the position of the valve 51 with respect to the seat 50, by means of the screw 52, the length of time that the mixture of water flows, being. governed by the position of the valve 51 with respect to the seat 50. The relative proportions of hot and cold water, and the total. amount of water delivered, may be adjusted by regulating the positions of the valves 15 and 47.

Referring to Figures 5, 6 and 7, the nu meral 61 marks a bowl carried by a back 62. The numeral 63 marks a tubular casing. The upper end ofthe casing 63 is stopped by a movable closure plug 64;. Near to its lower end, the casing has an outstanding flange 65. The casing 63 is supplied with a reduced neck 66. The neck 66 extends downwardly through the lip of the washbowl 61. A nut 67 is threaded on the neck 66. Packing washers 68 are interposed between the neck 66 and the lip of the washbowl, and between the lip oi the washbowl and the flange 65. The casing 63 carries an out standing spigot 69 which discharges into the bowl 61,.the spigot being prolonged bacle wardly into the casing 63 and terminating in an upstanding tubular seat 70. A seat 71 is disposed above the seat 7 O. The space between the seat 71 and the wall of the casing 63, communicates, asindicated'at 72, with a bore 73 in the neck 66. The space between the upstanding tubular seat 71 and the upstanding tubular seat communicates, as shown at 74:, with a bore 7 5 in the neck 66. A cold water inlet pipe 76 communicates with the bore 73. The hot water inlet pipe 77 communicates with the bore 75. A valve 78, under the control of an operator, is interposed in the pipe 76. A similar valve 79 is interposed in the pipe 77. A casing 63 is provided with a vertical passage 80, communicating at its lower end with the spigot At the upper end of the passage 80 there is an opening 81 which establishes communication between the passage 80 and the upper portion of the casing 63. The opening 81 is under the control of a valve 82. The valve 82 is carried by a stem 83. The stem 83 slides in a gland 84; assembled with the casing 63. There is an abutment 85 on the stem 83. A compression spring 86 is disposed about the stem 83. One end of the spring 86 enga es the abutment 85. The other end'oi" the spring 86 engages the casing 63 at a point adjacent to the opening 81. The function of the spring 86 is to hold the valve 82 closed with respect to the opening 81. v

A valve 87 is mounted for reciprocation in the casing 63. The valve 87 includes a body 88, preferably in the form of a disk. On the body 88 is located a washer 89 made of any suitable flexible material and having an upstanding marginal rim 90 which engages the inner surface of the casing 63. A washer 89 is held on the body 88 by a head 91, which may be in the form of a met-a1 disk, the head 91 having a tubular neck 92 extended through the washer 89 and through the body 88. In the upper surface of the head 91., there is a bore 93 having a lateral extension 9%, there being a seat 95 at the lower end 01 the bore 93, the seat 95 communicating with the bore 96 of the neck 92. A valve 97, preiterably in the form ojl a screw,is threaded into the bore 93 and may be adjusted, at the will of an operator, toward and away from the seat 95. A packing disk 98 is secured to the lower surface of the body 88 by means oi a screw 99 or its equivalent. NVhenthe valve 87 is in the lowest position of Figure 5, the disk 98, cooperating with the tubular seats 71 and 70, closes the spigot 69, and closes, also, the point of communication 74-, through which the hot water from the pipe 77 is discharged, the body portion 88 ot the valve 87 closing 08' the cold water communication at 7 2.

In practical operation, the valve 82 is thrust inwardly by means of the stem 83, the spring 86 being compressed. The spring 86 serves to close the valve 82 as soon as the stem 83 is released, but whilst the stem is under pressure at the hand of an operator. and whilst the valve 82 is open, the water in the casing 63, above the valve 87, flows through the opening 81, and through the passage 80, the water being discharged through the spigot 69, and the pressure above the valve 87 being relieved. The valve 87 then moves upwardly, because it has full water pressure beneath, derived from the pipes 76 and 77. When the valve 87 moves to open position,cold water flows upwardly through the pipe 76, and hot water flows u wardly through the pipe 77, the hot and cold water mixing in the casing 63, below the elevated valve 87, the mixture of hot water flowing outwardly through the spigot 69. After an interval of time, regulated and covered by the position of the valve 97 with respect to the seat 95, water flows into the casing 63, above the valve 87, and the valve 87 moves downwardly into the position shown in Figure 5, to out ofi" the supply or hot and cold water. The relative amounts of hot and cold water, and the total amount of water delivered, are regulated by adjusting one or both of the valves 78 and 79.

Referring to Figures 8 and 9, there is shown casings 100,-providedat their upper ends with removable closures 105, the casings communicating at their lower ends with a common spigot 101, adapted to discharge into a bowl 102. A pipe 103 communicates with eachof the casings 100, -andin each pipe 103 there is a'valve 104: under the control of an operator. The sliding valve appears at 106 and carries a time valve 107. A passage 108 leads from the" upper portion oi each casing to the lower portion thereof. The valve 106 cooperates with a tubular seat 112. A valve which controls tlie'flow of water from the upper part of the casing 100 through the passage 108, is marked by the numeral 109 and is carried by a stem 114, the closing springs being ma'rl'red by the numeral 110. The stems 1141 are'joined toithe yoke 111 provided with a handle'115.

The operation. of thcdevice will be understood readily from what has been stated hereinbel ore in connection with the other forms of the invention. By pushing the yoke 111 inwardly, a mixture 01' hot-and cold water is caused to flow tl'irou'gh' the spigot 101 until the valve 100 closes, as hereinbefore de scribed, the timing valve'107 being of the kind delineated in Figure 7, andoperating as set forth in that figure.

In Figure 10, the casings are shown at 116 and communicate with a spigot 117,"as in Figure 9. The casiiigs'llb are j oined at their upper ends by a Connection 118 located above the valves, which are constructed as shown at 106 in Figure 8. Water inletpipes appear at 119 and carry theregulatingyalve 120. A single push valve, indicated generally at 125, replaces the two valvesshown at 109 in Figure 8. i i i What is claimed is 1.
